Bed Rust

I have a 03 Tundra that has had the frame resprayed by dealer due to class action. My truck has always had a slide in liner and a full cap on it. I had never crawled under it to examine the underside. Well I removed the cap and the liner this week and found 13 spots on the bed deck that had rust spotting. Son small others large (size 1 to 1/2 inches). I have not pocked at them to see if they go thru. I did look underneath to see if maybe the spots were being rubbed against something that might have caused it. Nothing !! would the whole underside have been resprayed when the dealer resprayed for the class action suit.I have no other rust on truck.

 

I assume that by 'slide in liner', you mean those plastic liner that you put on top of the bed.

I would've been more surprised if your 14 year old truck bed had been pristine especially since you have had these liners. They are notoriously bad in collecting moisture and keeping it there.

If it's just surface rust, you could scrub the rust and repaint (or line x)

 

Line-x time!
